Yes I tried with the computer and the wifi and I have enough space on the mini. How many devices can you transfer your music on if they are registered to your account? It's my 4th one, is there a limit?

Congrats the problem resolved.
BTW, this iFunia iPad column and the iMore blog might can help you using the iPad more smoothly.
Of course, if you have any problem, you could turn to the Apple's discussions community.
